Item and asset creation flows attach value and metadata to new outputs. A client builds a request, signs with keys you control, and sends it through the mempool path. Field names in your SDK may differ; align with the version you have installed.
Relation to the API
The low-level HTTP shape is similar in spirit to create_item_asset. A typical wallet SDK abstracts this into fewer parameters and enforces your policy (fees, change addresses, and dry-run).
Validation
Always test on a test network or a local stack before you move real value.
